1. Electron crystallography : methods and applications for biological and inorganic crystals and quasicrystals
Sammanfattning : .... LÄS MER
2. 3D Electron crystallography : Real space reconstruction and reciprocal space tomography
Sammanfattning : Electron crystallography is an important technique for studying micro- and nano-sized materials. It has two important advantages over X-ray crystallography for structural studies: 1) crystals millions of times smaller than those needed for X-ray diffraction can be studied; 2) it is possible to; focus the electrons to form an image.

3. Exploiting reciprocal space : Electron diffraction, textures and precession
Sammanfattning : Electron crystallography emerges as a new tool for accurate structure determination of very small crystals. In order to exploit the full potential of electron diffraction, the methods for data acquisition and processing have to be developed towards the high standards of X-ray crystallography. LÄS MER
4. A journey towards complete structure determination of zeolites by electron crystallography methods
Sammanfattning : Electron crystallography has recently become very successful for structural studies of materials with sub-micrometer sized crystals. In this thesis two major techniques have been applied for structure elucidation – 3-dimensional electron diffraction (3D ED) and high-resolution transmission electron microscopy (HRTEM) imaging.

5. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination
Sammanfattning : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.
